r i The` Schedule referred to in these Letters Patent and making part of the sama.

I, GLEAVELAND F. DUNDERDALE, of New York city, in the county and State. of New York, have invalve, and a piperconnected with a receiver, to contain a supply of air under pressure, which is placed on topl of a railroad car or locomotive, and arranged in such almanner that the moving of the car or locomotive causes a pressure of air down the pipe leading from the blower into the receiver, where it is kept under pressure, and distributed through pipes leading thereu from to a suitable cai'hureting device for carbureting the same with 'ithe vapors of a hydrocarbon liquid placed therein for producing an illuminating gas,or for heat ing purposes.` i

. Figure lis aside elevation of a machine embodying my invention. l

r A are the funnel-shapedblowers, placed parallel `with Ithexnoving car or locomotive, having a wide trumpet mout-l1 on each, which meet into one pipe at B. The motion of the car 'causes `a current ol' air to-pass down the funnel into pipe Bf l,

G is a swinging valve, placed between the two blowers, so that a current of air passing inA one blower causes the valve to swing against the other Ablower opening, preventing its passing directly through and 'detlecting it downward into pipe B.

D is` a trap, arranged to collectdust and cnders' that `may be -blown down. Y

E is a'wireganze, placed npipeF to sift the air Aof its particles of dust.

y G, isa receiver, made like a bellows, to rise and fall according to the quantity of ail-.contained.therein.` H is a cord or chain, attached at its upper end to the inside top of the bellows receiver, having its lower end fastened to avalve shown at I, which, when the bellows-top rises to its full extent, the tightening-cord -lifts the valve I, and permits the excess of air to pass ont,lthereby preventing a great strain on the sides of the bellows receiver.

.I is a pipe'leadingffiom the-receiver to the vessel containing the hydrocarbon liquid, where it is to be 'carbureted, and-from thence passes to the burners,

where it is to be consumed.

A single rotary funnel blower may be used instead of a double one, whieh'wonld be stationary, In using a single'blower, a large fan-tail rudder would be necessary to keep the mouth of the blower to the wind.

The operation is, that when a train or car starts,

the motion thereof causes a current of air to pass in the 'funnel A, causing valve C to swing to the opposite side. The air is thence deflected into pipe B; passing down the same, enters pipe F, passing through the seive E, which precipitates the dust into trap I).

Passing through pipe F the air enters the bellows G, inflatiug the same, which, on rising to its full extent, opens by means of oord H the valve I, when the air then passes out through said valve until the air is di awn out from the bellows receiver vthrough pipe J,

when the valve closes, and the receiveris again filled' as fast as drawn ofi'. The receiver 'is made of suiicient size to contain enough air to supply the burners for that length ot' time.

I claim yas my invention;-

1. Using the motion of railroad-trains, while moving, for forcing the atmosphericair, by atmospheric resistance, into a receiver for holding the air, and giving a steady pressure thereto for the purpose of carf bureting the same for illuminating, heating, 85o., substantially. as and for the purpose hereinbef'ore set forth .v

2. 'lhe blower `A or' its equivalent, the valve C or its equivalent, pipe B, trap D, seive E or its equivalent, pipe Ii, receiver G with cord and valve H and I or their equivalents, and outlet-pipe J, when arranged substantially as and for the purpose hereinbefore set forth. v

3. The above, in combination with any 'air-carbufor several hours, should the motion of the Vcar cease .reting device for carbnreting atmospheric air for illuminating, heating, and other purposes.
